Definitions
- This invention generally relates to a clipless or step-in bicycle pedal. More specifically, the present invention relates to a bicycle pedal that engages a cleat secured to the sole of a bicycle shoe.
- a step-in or clipless pedal is releasably coupled to a cleat that is secured to the sole of a cyclist's shoe.
- the bottom of the cyclist's shoe is fixed to the pedal for transmitting the pedaling force from the cyclist to the pedal of the bicycle.
- clipless pedals the shoes and the pedals are in a state of constant engagement when the cleats are engaged in the cleat clamping members, so the pedaling force can be transmitted efficiently to the pedals.
- clipless pedals are widely employed on racing bicycles used in road racing and off-road bicycles used in mountain bike racing.
- the clipless or step-in pedal has a pedal spindle that can be mounted on the crank of a bicycle, a pedal body that is rotatably supported on this pedal spindle, and a cleat engagement mechanism.
- a cleat engagement mechanism is formed on both sides of the pedal body.
- Each cleat engagement mechanism has a pair of cleat clamping members that are fixed on one of the sides of the pedal body for engaging front and rear portions of a cleat.
- Road racing pedals typically only have a cleat engagement mechanism on one side of the pedal body. In either case, in this type of bicycle pedal, the rider steps onto the pedal and the cleat engagement mechanism automatically grips on to the cleat secured to the bottom of the cyclist's shoe.
- the cyclist when attaching the cyclist's shoe to the clipless or step-in pedal via the cleat, the cyclist moves the shoe obliquely downwardly and forwardly relative to the pedal body such that the front end of the cleat engages a front hook or clamping member of the pedal body.
- the cyclist places the rear end of the cleat in contact with a guide portion of the rear hook or clamping member of the pedal body. In this position, the cyclist presses the shoe downwardly against the pedal to cause the rear hook or clamping member to initially pivot rearwardly against the force of a spring to move the rear hook or clamping member to a cleat releasing position.
- the rear end of the cleat then enters a position opposite a back face of the rear hook or clamping member. Then, the rear hook or clamping member returns under the force of a biasing member or spring so that the rear hook or clamping member engages the rear end of the cleat. This engagement fixes the cyclist's shoe to the pedal via the cleat.
- the cyclist When releasing the shoe from the pedal, the cyclist will typically turn the shoe about an axis perpendicular or approximately perpendicular to the tread of the pedal, using the front end of the cleat as a pivoting point. As a result of this pivoting action, the rear hook or clamping member is pivoted rearwardly against the force of the spring to a cleat releasing position to release the shoe.
- the pedal When clipless or step-in pedals are used for road type bikes, the pedal is typically only provided with a single clamping assembly such that the cyclist's shoe can only be coupled to one of the two sides of the pedal.
- Off-road or mountain type bikes usually have a pair of clamping assemblies such that the cyclist's shoe can be clamped to either side of the pedal. In either case, it is desirable to design the pedal to be as compact and lightweight as possible.
- clipless or step-in pedals can malfunction if dirt or mud gets into the cleat engagement mechanism. Once the cleat clamping members become dirty or clogged with mud, the cleat cannot be engaged in the cleat clamping members, and the shoe cannot be attached to the pedal. Specifically, the dirt or mud often clogs the biasing mechanism such that the clamping members may not operate properly.
- One object of the present invention is to provide a clip-less or step-in bicycle pedal that is inexpensive to manufacture.
- Another object of the present invention is to provide a clip-less or step-in bicycle pedal that operates well in dirty and muddy environments.
- Another object of the present invention is to provide a bicycle pedal with an improved releasing action between the bicycle pedal and the cleat.
- Another object of the present invention is to provide a bicycle pedal that is relatively lightweight.
- Another object of the present invention is to provide a bicycle pedal in which the clamping members are easily exchangeable.
- a bicycle pedal adapted to be coupled to a shoe via a cleat is provided as defined in claim 1. Further embodiments of the bicycle pedal are given in the dependent claims.
- Bicycle pedal 10 is a clipless or step-in pedal that can be used with a bicycle shoe 12 with a cleat 14 coupled thereto.

- the stop pin 80 can be press-fitted or bonded to support members 58 and 60.
- stop pin 80 can be eliminated by configuring the pedal body 22 so as to perform the function of the stop pins, i.e., pre-loading second clamping member 26 so that second clamping member 26 is not loosely coupled to pedal body 22.
- rear clamping member 26 is preferably a one-piece, unitary member that is formed of a resilient wire.

More specifically, the sole 18 of the shoe 12 is located closer to the longitudinal axis A of spindle 20 than in prior art pedals in which both of the cleat engagement surfaces are located above the plane of the cleat seat or plate 64.
- biasing portions 104 normally urge the retaining portion 102 of the clamping member 26 about its pivot axis A from its cleat releasing position to a cleat engaging or retaining position. In other words, biasing portions 104 normally maintain clamping member 26 in its cleat engaging or cleat retained position as seen in Figures 6 and 8.

- Projections 72 are wedged between coiled sections 112 and coupling arms 114 to relative limit movement between rear clamping member 26 and pedal body 22.
- rear clamping member 26 is releasably coupled to pedal body 22, rear clamping member 26 can be easily replaced if it becomes damaged or a spring with a different spring force is needed and/or desired.
- the second arms 116 extending between the coiled sections 112 and the cleat retaining portion 102 to form a U-shaped hook or clamp.
- the second arms 116 also engage stop pin 80 such that the coiled sections 112 are pre-loaded as seen in Figure 6.
- Figures 9-12 illustrate the rear clamping member 26 in an unloaded state.
- the cleat receiving section 106 is curved with a concaved cleat restricting surface facing towards the first clamping member 24.
- the cleat receiving section 106 is designed to engage a coupling portion 38 of cleat 14.
- Cleat receiving section 106 limits rearward movement of cleat 14 as well as limits the amount of side-to-side movement of the cleat 14 relative to the pedal body 22.
- the concaved surface of the cleat receiving section 106 is spaced approximately 55-60 millimeters from the concaved surface of the cleat restricting surface 78 of the front clamping member 24.
- the spacing between the concaved cleat restricting surfaces of the clamping members 24 and 26 is spaced approximately 57 millimeters ⁇ 0.2 millimeters when the cleat 14 is not engaged between the clamping members 24 and 26.
- the longitudinal spacing between the concaved curved surfaces of the cleat receiving sections of the first and second clamping members 24 and 26 is approximately 57.5 millimeters ⁇ 0.05 millimeters.
- the cleat 14 has a longitudinal length that is approximately 0.5 millimeters larger than the longitudinal distance between the concaved cleat restricting surfaces of the first and second clamping members 24 and 26 so that when the cleat 14 is engaged therebetween, the biasing portions 104 apply a forward restraining force to limit longitudinal movement of the cleat 14 relative to the pedal body 22.
- Cleat 14 then slides past the cleat restricting sections 108. Once the cleat 14 has slid past the cleat restricting sections 108, the biasing force of the coiled sections 112 causes the retaining portion 102 to spring back almost to its original position. Since the front facing curved surface of cleat receiving section 106 contacts the rear coupling portion 38 of cleat 14, rear clamping member 26 cannot return completely to its original position.
- the stop surfaces 40 and 44 are designed to engage the cleat restricting surfaces of the first and second clamping members 24 and 26 for limiting relative longitudinal movement.
- the front stop surface 40 of cleat 14 also acts as a pivot point for releasing cleat 14 from pedal body 22.
- the coiled sections 112 are preferably slightly more compressed than their original state to apply a forwardly directed force on cleat 14.
- cleat 14 is held against longitudinal movement between the curved cleat restricting surfaces of the first and second clamping members 24 and 26.
- vertical movement of cleat 14 is prevented because cleat 14 is sandwiched between the cleat receiving surface 66 and the first and second cleat engagement surfaces 76 and 110.
- a bicycle pedal 10' in accordance with a second embodiment of the present invention is illustrated.
- the bicycle pedal 10' of the second embodiment is substantially identical to the bicycle pedal 10 the first embodiment. Therefore, bicycle pedal 10' will not be discussed or illustrated in detail herein.
- the only significant difference between this second embodiment and the first embodiment is that stop pin 80 of the first embodiment has been replaced with a pair of stop pins 80a. Accordingly, the same reference numerals will be used in Figures 16 and 17 to indicate the parts of the bicycle pedal 10' of this second embodiment are the same parts in the first embodiment.
- the stop pin 80 of the first embodiment has been replaced with a pair of stop pins 80a.
- the stop pins 80a of the second embodiment are inserted into the throughbores 80b formed in support members 58 and 60, respectively.
- the bore 80b in support member 58 of the second embodiment is preferably a mirror image of the bore 80b formed in support member 60.
- one of the stop pins 80a is inserted into the bore 80b formed in support member 58 and the other stop pin 80a is inserted into the bore 80b formed in support member 60.
- the stop pins 80a are knurled at one end and press-fitted into the bores 80b that are formed in support members 58 and 60.
- the stop pins 80a perform the same function as the stop pin 80 of the first embodiment. However, the use of a pair of stop pins 80a can make the bicycle pedal easier to assemble or manufacture. Since the operation of the bicycle pedal 10' of this second embodiment is the same as the operation of the bicycle pedal of the first embodiment, the second embodiment will not be discussed in further detail herein.

Abstract
Description
- This invention generally relates to a clipless or step-in bicycle pedal. More specifically, the present invention relates to a bicycle pedal that engages a cleat secured to the sole of a bicycle shoe.
- In recent years, bicycle pedals have been designed for specific purposes such as for comfort, recreational biking, off-road biking, road racing, etc. One particular type of bicycle pedal, which is gaining more popularity, is the step-in or clipless pedal. A step-in or clipless pedal is releasably coupled to a cleat that is secured to the sole of a cyclist's shoe. Thus, the bottom of the cyclist's shoe is fixed to the pedal for transmitting the pedaling force from the cyclist to the pedal of the bicycle. In other words, with clipless pedals, the shoes and the pedals are in a state of constant engagement when the cleats are engaged in the cleat clamping members, so the pedaling force can be transmitted efficiently to the pedals. As a result, clipless pedals are widely employed on racing bicycles used in road racing and off-road bicycles used in mountain bike racing.
- The clipless or step-in pedal has a pedal spindle that can be mounted on the crank of a bicycle, a pedal body that is rotatably supported on this pedal spindle, and a cleat engagement mechanism. In an off-road bicycle pedal, a cleat engagement mechanism is formed on both sides of the pedal body. Each cleat engagement mechanism has a pair of cleat clamping members that are fixed on one of the sides of the pedal body for engaging front and rear portions of a cleat. Road racing pedals typically only have a cleat engagement mechanism on one side of the pedal body. In either case, in this type of bicycle pedal, the rider steps onto the pedal and the cleat engagement mechanism automatically grips on to the cleat secured to the bottom of the cyclist's shoe.
- More specifically, when attaching the cyclist's shoe to the clipless or step-in pedal via the cleat, the cyclist moves the shoe obliquely downwardly and forwardly relative to the pedal body such that the front end of the cleat engages a front hook or clamping member of the pedal body. Once the front end of the cleat is engaged with the front hook of the pedal body, the cyclist places the rear end of the cleat in contact with a guide portion of the rear hook or clamping member of the pedal body. In this position, the cyclist presses the shoe downwardly against the pedal to cause the rear hook or clamping member to initially pivot rearwardly against the force of a spring to move the rear hook or clamping member to a cleat releasing position. The rear end of the cleat then enters a position opposite a back face of the rear hook or clamping member. Then, the rear hook or clamping member returns under the force of a biasing member or spring so that the rear hook or clamping member engages the rear end of the cleat. This engagement fixes the cyclist's shoe to the pedal via the cleat.
- When releasing the shoe from the pedal, the cyclist will typically turn the shoe about an axis perpendicular or approximately perpendicular to the tread of the pedal, using the front end of the cleat as a pivoting point. As a result of this pivoting action, the rear hook or clamping member is pivoted rearwardly against the force of the spring to a cleat releasing position to release the shoe.
- When clipless or step-in pedals are used for road type bikes, the pedal is typically only provided with a single clamping assembly such that the cyclist's shoe can only be coupled to one of the two sides of the pedal. Off-road or mountain type bikes, on the other hand, usually have a pair of clamping assemblies such that the cyclist's shoe can be clamped to either side of the pedal. In either case, it is desirable to design the pedal to be as compact and lightweight as possible.
- One problem with clipless or step-in pedals is that they can malfunction if dirt or mud gets into the cleat engagement mechanism. Once the cleat clamping members become dirty or clogged with mud, the cleat cannot be engaged in the cleat clamping members, and the shoe cannot be attached to the pedal. Specifically, the dirt or mud often clogs the biasing mechanism such that the clamping members may not operate properly.
- Closest prior art document German utility model DE 91 04 710 which discloses all the features of the preamble of independent claim 1, discloses a pedal arrangement by which the front and rear clamping members are formed as wire clamping elements. The rear clamping element is spring-biased by first and second coil spring sections, which are anchored through coupling arms to the pedal body.
- One object of the present invention is to provide a clip-less or step-in bicycle pedal that is inexpensive to manufacture.
- Another object of the present invention is to provide a clip-less or step-in bicycle pedal that operates well in dirty and muddy environments.
- Another object of the present invention is to provide a bicycle pedal with an improved releasing action between the bicycle pedal and the cleat.
- Another object of the present invention is to provide a bicycle pedal that is relatively lightweight.
- Another object of the present invention is to provide a bicycle pedal in which the clamping members are easily exchangeable.
- According to the present invention as disclosed by the features of the characterizing portion of independent claim 1, a bicycle pedal adapted to be coupled to a shoe via a cleat is provided as defined in claim 1. Further embodiments of the bicycle pedal are given in the dependent claims.

- Figure 14 is a longitudinal cross-sectional view of the bicycle pedal illustrated in Figure 13 as seen along section line 14-14 of Figure 13 in accordance with a second embodiment of the present invention.
- Referring initially to Figures 1 through 8, a
bicycle pedal 10 is illustrated in accordance with the first embodiment of the present invention.Bicycle pedal 10 is a clipless or step-in pedal that can be used with abicycle shoe 12 with acleat 14 coupled thereto.Bicycle pedal 10 is especially designed for use with a road bicycle as opposed to use with an off-road bicycle. Of course,bicycle pedal 10 can be used on any type of bicycle if needed and/or desired. Moreover,bicycle pedal 10 can be constructed as an off-road pedal such thatcleat 14 can be attached to either side ofbicycle pedal 10. As seen in Figures 1 and 3,bicycle pedal 10 is fixedly coupled tobicycle crank arm 16 of a bicycle for rotation therewith, whilecleat 14 is fixedly coupled to the bottom of sole 18 of ashoe 12. -
Bicycle pedal 10 illustrated in Figures 1 through 8 is a right side pedal. Of course, the same pedals are provided on the right and left sides of the bicycle, except that theleft side pedal 10 is a mirror image of theright side pedal 10. Thus, it will be apparent to those skilled in the art that the description of theright pedal 10 also applies to a left pedal. - As seen in Figures 1, 2 and 4,
bicycle pedal 10 basically includes a pedal shaft orspindle 20 adapted to be coupled tocrank arm 16 and apedal body 22 rotatably coupled tospindle 20 for supporting a cyclist's foot. Pedalbody 22 basically includes afirst clamping member 24 andsecond clamping member 26. The first orfront clamping member 24 is fixed topedal body 22 to form a stationary clamping member. The second orrear clamping member 26 is movably coupled topedal body 22 without using any fasteners, as discussed below in more detail. -
Cleat 14 is designed to releasably couple sole 18 ofshoe 12 tobicycle pedal 10 by first andsecond clamping members cleat 14 is engaged withpedal 10 by pressingcleat 14 intopedal 10 with a forward and downward motion. This releasably lockscleat 14 to pedal 10.Cleat 14 can be released frompedal 10 by twisting the heel of theshoe 12 to the outside ofpedal 10 as discussed below in more detail. - Referring to Figure 3,
bicycle shoe cleat 14 is fixed to sole 18 ofshoe 12 by a pair of screws orfasteners 32 in a conventional manner. Sincepedal cleat 14 is relatively conventional and its specific construction is not critical to the present invention, the construction ofcleat 14 will not be discussed in detail herein. Whilecleat 14 is illustrated as a one-piece member, it will be apparent to those skilled in the art from this disclosure that cleat 14 can be constructed of several separate pieces. - Basically, cleat 14 of the illustrated embodiment includes a
middle attachment portion 34, afront coupling portion 36 extending from one end of theattachment portion 34 and asecond coupling portion 38 extending from the other end of theattachment portion 34. In the illustrated embodiment, thefirst coupling portion 36 is a front coupling member that engages the front clampingmember 24, while thesecond coupling portion 38 is a rear coupling member that engages the clampingmember 26. -
Attachment portion 34 has an upper sole side facing in a first direction for engaging sole 18 ofshoe 12 and a lower side facing in a second direction, which is substantially opposite to the first direction. Preferably,attachment portion 34 andcoupling portions cleat 14 can be constructed from a metallic material, which is stamped from a sheet metal material, or cast or machined. -
Front coupling portion 36 ofcleat 14 forms a front nose portion with acurved stop surface 40 and afirst coupling surface 42. Therear coupling portion 38 ofcleat 14 forms a rear heel portion with acurved stop surface 44 and asecond coupling surface 48. The first and second coupling surfaces 42 and 48 face substantially in the same direction for engaging the first andsecond clamping members second clamping members front stop surface 40 ofcleat 14 also acts as a pivot point for releasingcleat 14 frompedal body 22. - Referring again to Figures 1 through 3,
pedal spindle 20 has afirst end 50 with threads formed thereon forthreadedly coupling pedal 10 to crank 16 in a conventional manner. As seen in Figures 6 and 8, the other orsecond end 52 ofpedal spindle 20 rotatably supportspedal body 22 in a conventional manner, e.g. via bearings (not shown).Pedal body 22 can freely rotate about the center longitudinal axis A ofpedal spindle 20. Sincepedal spindle 20 is relatively conventional and its specific construction is not critical to the present invention, the construction ofpedal spindle 20 will not be discussed in detail herein. -
Pedal body 22 is preferably made of a lightweight material such as an aluminum alloy. Preferably, one of the clampingmembers pedal body 22 as best seen in Figures 2 through 5.Pedal body 22 has a main center longitudinal axis B extending between the front and the rear ends as seen in Figures 2 and 5. Center longitudinal axis B ofpedal body 22 extends substantially perpendicular to center longitudinal axis A ofpedal shaft 20. As shown in Figure 2 and 5,pedal body 22 has a main frame with acenter tubular portion 54, a curvedfront end portion 56 extending from centertubular portion 54, and a pair ofsupport members pedal body 22.Pedal spindle 20 is received in abore 62 formed in centertubular portion 54 so thatpedal body 22 rotates about center longitudinal axis A. - A cleat seat or
plate 64 is coupled to centertubular portion 54 by three screws orfasteners 65.Cleat seat 64 has a flat uppercleat receiving surface 66 for supportingcleat 14. Thecleat receiving surface 66 lies in a plane P1 as seen in Figure 6. - A cleat receiving area is formed between clamping
members cleat 14 to pedalbody 22. First clampingmember 24 is fixedly coupled to thefront end portion 56 ofpedal body 22 via a pair of screws orfasteners 68 as seen in Figure 5. Therear clamping member 26 is fixedly coupled in the space betweensupport members pedal body 22. Specifically,rear clamping member 26 is releasably retained by the spring force of the wire in a pair ofnotches 70 that are formed in a pair of projections 72extending fromsupport members member 26 can be releasably coupled topedal body 22 by other means such as friction or a press fit. Sincerear clamping member 26 is releasably coupled topedal body 22,rear clamping member 26 can be easily replaced if it becomes damaged or a spring with a different spring force is needed and/or desired. - First clamping
member 24 is preferably constructed of a separate member that is fixedly secured to the bottom ofpedal body 22 byscrews 68 as seen in Figure 5. Of course, it will be apparent to those skilled in the art from this disclosure that first clampingmember 24 can be formed as a unitary part ofpedal body 22. Preferably, first clampingmember 24 is constructed of a metallic sheet material such as stainless steel or other non-corrosive materials. First clampingmember 24 has a pair of mountingflanges 74 with holes for receiving fasteners or screws 68 to fixedly secure first clampingmember 24 topedal body 22. - The
first clamping member 24 is configured to form a firstcleat engagement surface 76 and a firstcleat restricting surface 78. Thecleat engagement surface 76 lies in a plane P2 that is substantially parallel to the plane P1 of thecleat receiving surface 66. Plane P2 of thecleat engagement surface 76 is closer to the longitudinal axis A ofspindle 20 than the plane P1 of thecleat receiving surface 66. Thecleat engagement surface 76 is designed to engagefirst coupling surface 42 ofcleat 14 so that the pedaling force can be transmitted from the cyclist to thepedal 10. - The
cleat restricting surface 78 is a curved surface that preferably lies substantially perpendicular to the plane P2 of thecleat engagement surface 76. Thecleat restricting surface 78 limits forward movement of thecleat 14 by engagingcurved stop surface 40 ofcleat 14.Cleat restricting surface 78 also acts as a pivoting point forcleat 14 during a releasing motion ofcleat 14 relative topedal body 22. Preferably,cleat restricting surface 78 is a concaved surface that faces towards thesecond clamping member 26. Thus, curvedcleat restricting surface 78 forms a cleat receiving recess that receives the front nose a portion ofcleat 14 therein. - Turning now to rear clamping
member 26,support members pedal body 22 extend rearwardly from centertubular portion 54 and are laterally spaced apart for receivingrear clamping member 26 therebetween. - A
stop pin 80 extends betweensupport members member 26 so that second clampingmember 26 is not loosely coupled topedal body 22. Stoppin 80 has its first end located in a bore ofsupport member 58, while its second end is located in a bore ofsupport member 60. Preferably, the bore insupport member 58 is a throughbore, while the bore of thesupport member 60 is a blind bore to provide an attractive outward appearance along the outside surface ofpedal 10. The blind bore of thesupport member 60 can be threaded to secure thestop pin 80 betweensupport members pin 80 can be securely fastened betweensupport members stop pin 80 can be press-fitted or bonded to supportmembers pin 80 can be eliminated by configuring thepedal body 22 so as to perform the function of the stop pins, i.e., pre-loading second clampingmember 26 so that second clampingmember 26 is not loosely coupled topedal body 22. - As best seen in Figures 9 through 12,
rear clamping member 26 is preferably a one-piece, unitary member that is formed of a resilient wire. The wire ofrear clamping member 26 preferably has a circular cross-section so that the curvature of the wire acts as a guide surface. Clampingmember 26 has acenter retaining portion 102 and a pair of biasingportions 104 coupled to the ends of retainingportion 102. Retainingportion 102 extends from biasingportions 104 in a direction transverse to the center longitudinal axis B ofpedal body 22. - Retaining
portion 102 has acleat receiving section 106 formed at its center. The retainingportion 102 also includes a pair ofcleat restricting sections 108 located on the sides of thecleat receiving section 106. Thecleat restraining sections 108 are configured and arranged to limit vertical movement of thecleat 14 relative to cleat receivingsurface 66 of thepedal body 22. - The
cleat restricting sections 108 engagecoupling surface 48 of thecleat 14. More specifically,cleat restricting sections 108 form asecond engagement surface 110. Thesecond engagement surface 110 lies in a plane P3 that is parallel to planes P1 and P2. The plane P3 is located above the plane P1 of thecleat receiving surface 66. In other words, the first and second cleat engagement surfaces 76 and 110 face in substantially the same direction and lie on opposite sides of the plane P1 of thecleat receiving surface 66. This arrangement provides for efficient transfer of the pedaling force from the cyclist to the pedals. More specifically, the sole 18 of theshoe 12 is located closer to the longitudinal axis A ofspindle 20 than in prior art pedals in which both of the cleat engagement surfaces are located above the plane of the cleat seat orplate 64. - The biasing
portions 104 normally urge the retainingportion 102 of the clampingmember 26 about its pivot axis A from its cleat releasing position to a cleat engaging or retaining position. In other words, biasingportions 104 normally maintain clampingmember 26 in its cleat engaging or cleat retained position as seen in Figures 6 and 8. Each of the biasingportions 104 has a coiledsection 112, acoupling arm 114, and asecond arm 116. - The coupling
arms 114 extend from the coiledsection 112 and engage thenotches 70 of thepedal body 22 to releasably couplerear clamping member 26 topedal body 22. Preferably, couplingarms 114 are L-shaped members.Rear clamping member 26 is releasably retained by squeezing the couplingarms 114 together and then insertingcoupling arms 114 betweenprojections 72 so that they align withnotches 70. The couplingarms 114 are then released so that they spring outwardly intonotches 70. Thus, the spring force of the couplingarms 114 holds them innotches 70 as seen in Figure 5.Projections 72 are wedged between coiledsections 112 and couplingarms 114 to relative limit movement betweenrear clamping member 26 andpedal body 22. - Since
rear clamping member 26 is releasably coupled topedal body 22,rear clamping member 26 can be easily replaced if it becomes damaged or a spring with a different spring force is needed and/or desired. - The
second arms 116 extending between thecoiled sections 112 and thecleat retaining portion 102 to form a U-shaped hook or clamp. Thesecond arms 116 also engagestop pin 80 such that thecoiled sections 112 are pre-loaded as seen in Figure 6. Figures 9-12 illustrate therear clamping member 26 in an unloaded state. - The
cleat receiving section 106 is curved with a concaved cleat restricting surface facing towards the first clampingmember 24. Thecleat receiving section 106 is designed to engage acoupling portion 38 ofcleat 14.Cleat receiving section 106 limits rearward movement ofcleat 14 as well as limits the amount of side-to-side movement of thecleat 14 relative to thepedal body 22. Preferably, the concaved surface of thecleat receiving section 106 is spaced approximately 55-60 millimeters from the concaved surface of thecleat restricting surface 78 of the front clampingmember 24. In the most preferred embodiment, the spacing between the concaved cleat restricting surfaces of the clampingmembers cleat 14 is not engaged between the clampingmembers cleat 14 is engaged with the clampingmembers second clamping members cleat 14 has a longitudinal length that is approximately 0.5 millimeters larger than the longitudinal distance between the concaved cleat restricting surfaces of the first andsecond clamping members cleat 14 is engaged therebetween, the biasingportions 104 apply a forward restraining force to limit longitudinal movement of thecleat 14 relative to thepedal body 22. - Operation of
pedal 10 will now be briefly described with particular reference to Figures 7 and 8. Whenbicycle shoe 12 is attached to thepedal 10, the tip of theshoe 12 is moved forward towards the front clampingmember 24. Once the tip or front nose portion of thecleat 14 has been inserted underneath the first clampingmember 24, a downward force is applied to the heel side of theshoe 12, such that theshoe 12 is pushed downwardly towards thepedal 10. When the heel is pressed down further from this initial state, the rear heel portion of thecleat 14 contacts the retainingportion 102 of therear clamping member 26 to force it rearwardly. This causes retainingportion 102 to rotate about the main axis C against the biasing forces of thecoiled sections 112. -
Cleat 14 then slides past thecleat restricting sections 108. Once thecleat 14 has slid past thecleat restricting sections 108, the biasing force of thecoiled sections 112 causes the retainingportion 102 to spring back almost to its original position. Since the front facing curved surface ofcleat receiving section 106 contacts therear coupling portion 38 ofcleat 14,rear clamping member 26 cannot return completely to its original position. The stop surfaces 40 and 44 are designed to engage the cleat restricting surfaces of the first andsecond clamping members front stop surface 40 ofcleat 14 also acts as a pivot point for releasingcleat 14 frompedal body 22. Preferably, thecoiled sections 112 are preferably slightly more compressed than their original state to apply a forwardly directed force oncleat 14. As a result,cleat 14 is held against longitudinal movement between the curved cleat restricting surfaces of the first andsecond clamping members cleat 14 is prevented becausecleat 14 is sandwiched between thecleat receiving surface 66 and the first and second cleat engagement surfaces 76 and 110. - When the
shoe 12 is to be removed from the pedal, the heel portion of theshoe 12 is twisted to the outside. This twisting motion causes thecleat 14 to pivot about the curvedcleat restricting surface 78 of the first clampingmember 24, while the rear end of thecleat 14 moves outwardly relative to thepedal body 22. This twisting motion will cause the retainingportion 102 to rotate against the energizing force of thecoiled sections 112 of therear clamping member 26. During this twisting ofcleat 14 relative topedal body 22, the first andsecond biasing portions 104 apply substantially the same force on the retainingportion 102 to control the releasing force required to releasecleat 14 frompedal 10. After sufficient twisting ofcleat 14, the engagement of the rear end of thecleat 14 will be released and thecleat 14 can be removed from thepedal 10. - Referring to Figures 13 and 14, a bicycle pedal 10' in accordance with a second embodiment of the present invention is illustrated. The bicycle pedal 10' of the second embodiment is substantially identical to the
bicycle pedal 10 the first embodiment. Therefore, bicycle pedal 10' will not be discussed or illustrated in detail herein. Basically, the only significant difference between this second embodiment and the first embodiment is thatstop pin 80 of the first embodiment has been replaced with a pair ofstop pins 80a. Accordingly, the same reference numerals will be used in Figures 16 and 17 to indicate the parts of the bicycle pedal 10' of this second embodiment are the same parts in the first embodiment. - As mentioned above, the
stop pin 80 of the first embodiment has been replaced with a pair ofstop pins 80a. Preferably, the stop pins 80a of the second embodiment are inserted into thethroughbores 80b formed insupport members bore 80b insupport member 58 of the second embodiment is preferably a mirror image of thebore 80b formed insupport member 60. Thus, one of the stop pins 80a is inserted into thebore 80b formed insupport member 58 and theother stop pin 80a is inserted into thebore 80b formed insupport member 60. Preferably, the stop pins 80a are knurled at one end and press-fitted into thebores 80b that are formed insupport members stop pin 80 of the first embodiment. However, the use of a pair ofstop pins 80a can make the bicycle pedal easier to assemble or manufacture. Since the operation of the bicycle pedal 10' of this second embodiment is the same as the operation of the bicycle pedal of the first embodiment, the second embodiment will not be discussed in further detail herein. - While only two embodiments have been chosen to illustrate the present invention, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made herein without departing from the scope of the invention as defined in the appended claims.
